Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Lightweight Portable Security?
Summarize this article for a 10 year old
Lightweight Portable Security (LPS) or Trusted End Node Security (TENS) was a Linux LiveCD (or LiveUSB) distribution. The application Encryption Wizard, originally bundled with TENS is still actively maintained. LPS and its successor TENS was developed and publicly distributed by the United States Department of Defense’s Air Force Research Laboratory[3] The live CD is designed to serve as a secure end node. The Air Force Research Laboratory actively maintained LPS and TENS from 2007 to 2021.[4] It can run on almost any x86_64 computer (PC or Mac).[5] LPS boots only in RAM, creating a pristine, non-persistent end node. It supports DoD-approved Common Access Card (CAC) readers, as required for authenticating users into PKI-authenticated gateways to access internal DoD networks.[6][7][8]

LPS turns an untrusted system (such as a home computer) into a trusted network client. No trace of work activity (or malware) can be written to the local computer's hard drive. As of September 2011 (version 1.2.5), the LPS public distribution includes a smart card-enabled Firefox browser supporting DoD's CAC and Personal Identity Verification (PIV) cards, a PDF and text viewer, Java, a file browser, remote desktop software (Citrix, Microsoft or VMware View), an SSH client, the public edition of Encryption Wizard and the ability to use USB flash drives. A Public Deluxe version is also available that adds LibreOffice and Adobe Reader software.
